A multi-mode space-borne Synthetic Aperture Radar (SAR) simulator is presented in this paper. The simulator is based on the Space-borne Radar Advance Simulator (SBRAS), and supports the parameter design, raw data simulation, data focusing and performance evaluation of strip-map mode, spotlight mode, sliding spotlight mode, ScanSAR mode, Terrain Observation by Progressive Scans (TOPS) mode and mosaic...
Software reliability allocation is a complicated multiple-criteria decision process which involves many factors such as cost, performance, functional complexity and testing. For medical devices, safety is an extremely critical factor that it must be emphasized in the system software development from the early stages. In this paper, we demonstrate an intuitive approach to incorporate safety into reliability...
At present, few methods of creating conceptual architecture have been proposed. What's more, they can't meet the requirements of dynamic Internet environment or software reuse. However, a newly proposed method in paper can adapt to various types of changes in the dynamic environment and can make design and implementation more convenient than traditional methods. Therefore, this paper verifies this...
The discriminability of spatial cues refers to the ability of the auditory system to catch any change of sounds. For half a century there were many methods to measure the Just Noticeable Difference(JND) which represents the sensitivity of spatial cue by audio system. The JND should be obtained by a large number of experiments and the results were much various by different people in different experiment...
At present, several feature meta-models have been come up with. However, they can't meet the requirements of dynamic Internet environment or software reuse. This paper proposes a feature meta-model based on ontology. In particular, it can adapt to various types of changes in the dynamic environment and can make design and implementation more convenient than traditional methods. Finally, we give out...
To address the pressures and challenges in e-government, the author introduced Cloud computing into e-government, proposed the concept of C-government with transparency, participation and collaboration, designed the Cloud architecture and layer implementation of C-government, presented a complete solution for C-government Cloud, and deployed its data, services and applications to remote “Cloud”.
This paper focuses on how to enhance the management and production level of agricultural enterprises by integrating existing network and information resources, using computer and network technologies. In our research, SOA is used for the construction of agricultural enterprise informatization, ORM technology is adopted to match Object-Oriented and relational Databases. As an example, we introduce...
At present, few methods of creating conceptual architecture have been proposed. What's more, they can't meet the requirements of dynamic Internet environment or software reuse. This paper comes up with a new method of generating conceptual architecture based on ontology, feature model and component in which a new feature meta-model is also been come up with. In particular, this architecture can adapt...
In view of the coexistence of multiple control systems in hydropower plant at present, the restrictions of the rate and reliability between the communications of simple bus such as MODBUS, and the limitations of the substantial data communications, this paper proposes a new program using OPC to realize the data transmission between the monitoring software of hydropower plant real-time monitoring system...
